C(G)-391 High Density Connector Right-Hand Mounted, Stubless Unit

1. General1.1 This document is a basic guide for installingthe Corning Cable Systems C(G)391 High DensityConnector. It applies only to C(G)-391 Connectorsthat do not have a cable stub, are mounted on right-hand side of the frame vertical mounting bar, andare frame grounded.

1.2 The C(G)-391 central office connector hasbeen designed to meet or exceed BellcoreSpecification TR-EOP-000164.

1.3 This document is being reissued to remove atool reference.

2. Installation StepsInstallation consists of eight sequential steps:

1. Temporary Mounting2. Installing Cable Stub3. Final Mounting4. Grounding5. Splicing Cable Stub6. Marking and Jumpering7. Inserting Protector Units8. Testing

3. Step 1—Temporary MountingThe C(G)-391 Connector comes with a temporaryfield stubbing kit that provides working access forfield installation of the cable stub (Figure 2).

3.1 Position field stubbing bracket on left side ofC(G)-391 Connector mounting bracket. Insert screw(provided with field stubbing bracket) through slotin C(G)-391 Connector mounting bracket and holein field stubbing bracket.

3.2 Insert two no.12 screws (provided with C(G)-391 mounting bracket) through slots in fieldstubbing bracket. Mount field stubbing bracket toright-hand side of frame vertical mounting bar.

4. Step 2—Installing Cable StubFollow local practices for installing the cable stub.

4.1 Remove back cover from C(G)-391 connector(Figure 3).

4.2 Feed 10-pair group of cable stub wiresthrough each of the ten vertical fanning holes(Figure 4).

4.3 Dress each 10-pair group of wires toappropriate row of OSP terminals (Figure 5).

4.4 Wire-wrap each pair of wires to respectiveterminal pins.

4.5 Replace back cover after all OSP terminalconnections have been made.

5. Step 3— GroundingThe C(G)-391 connector is designed for framegrounding, Follow local practices and procedures tocomplete grounding.

6. Step 4—Splicing Cable StubCable stub wiring uses standard cable wire colorcodes. Match stub pairs and follow local practicesfor splicing.

7. Step 5—Final Mounting7.1 After cable stub installation (Step 2), removefield stubbing bracket.

7.2 The C(G)-391 Connector mounting brackethas two slotted mounting holes and a half-hole ateach end. Insert no.12 screws (provided) throughone mounting hole and one half-hole, or throughtwo slotted mounting holes, and secure the C(G)-391 mounting bracket to the left-hand side of framevertical mounting bar (Figure 6).

NOTE: Mounting hole patterns may differ at the topand bottom of some tall, conventional main distributingframes’ vertical mounting bars. A special mountingbracket may be used to facilitate mounting the C(G)-391Connector in these applications (Figure 6 inset).

8. Step 6—Marking and JumperingJumper terminals consist of 20 rows of wire-wrapterminal pins. Each row of five terminals isidentified by a number for easy pair identification(Figure 7).

8.1 Use appropriate stenciling kit to mark cableand pair numbers. Mark cable ID near “CA” area attop of connector; mark ID near “PR” area at bottomof connector.

8.2 Insert two pairs of jumper wires intosecondary fanning strip slot (pairs one and two intop slot).

8.4 Dress each wire along bottom of appropriaterow of terminal pins.

8.5 Repeat steps above for remaining jumperpairs.

8.6 Dress wire slack to rear of C(G)-391connector. Jumper pairs should run neatly fromterminal field across connector backplane.

9. Step 7—Inserting ProtectorModulesThe protector field is located on the left side of theC(G)-391 Connector. Numbers at the top and rightside of the protector field identify wire pairs. Theprotector field is keyed so that protector modulescan only be installed one way (Figure 8).

NOTE: Use appropriate test set to check protectormodules for tip and ring continuity and ground.

Figure 8

9.1 Insert protector modules to “detent” positionduring installation (Figure 8 inset). Detent positionprotects OSP pairs, but keeps OSP pairsdisconnected from Central Office (CO) equipment.

9.2 After installation steps have been completed,push each protector unit into its fully insertedposition. This connects CO pairs to OSP pairs.

10. Step 8—Testing

Figure 9

The C(G)-391 test field consists of 100 pairs ofgold-plated contacts. Test points are connecteddirectly to OSP cable with separate connections fortip and ring of each pair. Test field terminals arenumbered to show beginning and end of each row offive terminals (Figure 9).

• 1,5

• 6,10

• 11,15 (through....)

• 96,00 (100)

Use Corning NT8G99AA Single-pair test cordor A0354444 100-pair test connector to testconnections.

NOTE: The C(G)-391 is also designed to be usedwith AT&T model P2FM single-pair test cord, andAT-8987 T-test connector.
